App rejected for using non-public API __SwiftValue in Runner – Swift runtime false positive?

Hello,

Our iOS app (Flutter + Swift) was rejected under Guideline 2.5.1 with the following message:

The app uses or references the following non-public or deprecated APIs: Runner Classes: __SwiftValue

From our investigation, __SwiftValue appears to be an internal Swift runtime class automatically generated by the Swift compiler for Swift–Objective-C bridging. It is not imported, referenced, or used directly in our source code.

We verified that: The symbol exists only in the compiled Runner binary

It is not referenced by any third-party framework explicitly

It appears in standard Swift runtime behavior

We previously removed a legitimate private API (PGHostedWindow) from a dependency and resubmitted, after which this new rejection appeared.

Questions:

Is __SwiftValue considered a private API usage by App Review, or is this a false positive?

Are there recommended build settings or mitigations to prevent this symbol from being flagged?

Should this be escalated for manual review?

Any guidance from Apple engineers or developers who encountered similar rejections would be greatly appreciated.

Thank you.
